BF-3 Basic Flasher Adjustable

BF-3 Basic Flasher Adjustable

Details:

The Circuitron BF-3 Adjustable Universal Flasher Circuit offers all the versatility of the popular BF-2 while adding fully adjustable flash timing and duty cycle control. Designed for modellers who require precise control over flashing effects, the BF-3 can be used with both incandescent lamps and LEDs, making it ideal for warning beacons, crossing signals, emergency vehicle lighting, industrial warning systems and a wide variety of animated scenic effects.

Two onboard miniature adjustment controls allow users to fine-tune both the flash rate and duty cycle. The flash frequency can be adjusted from a slow pulse of once every 10 seconds to dozens of flashes per second, providing exceptional flexibility for matching prototype lighting effects. At higher settings, connected lamps may appear continuously illuminated, making the BF-3 suitable for a broad range of custom lighting applications.

The adjustable duty cycle allows control of the amount of time the output remains on versus off during each cycle. This can be set anywhere between 5% and 95%, enabling everything from brief warning flashes to long-duration pulses. The result is a highly adaptable lighting controller capable of reproducing countless prototype and custom lighting effects.

Like the BF-2, the BF-3 operates from 8V to 18V AC or DC power sources and can control lighting circuits powered by separate voltages. Multiple lamp voltages can be operated from a single BF-3 provided all power supply grounds are connected together. This makes it an excellent choice for advanced lighting projects requiring maximum flexibility and control.
